Filed: 1991-06-24
Abstract: PURPOSE:To switch the gamma character without damaging the picture quality by absorbing the signal quantity change, which is caused by the change of the characteristic of a gamma correction circuit, by a gain varying circuit. CONSTITUTION:Light made incident from a lens 1 is photoelectrically converted by a sensor 3 and passes a gain varying circuit 4 and a signal processing circuit 14 and is outputted as a video signal. In this case, the gamma characteristic is switched for the purpose of optimizing the extent of gamma correction in accordance with the illuminance and the color temperature of an object; and a microcomputer 6 not only controls the gamma characteristic for a signal processing circuit 14 in accordance with data 12 but also controls a gain varying circuit 4 to keep the total signal quantity constant. That is, the AGC gain is reduced to reduce the input when an output 13 is increased by switching of the gamma characteristic, but the AGC gain is raised to increase the input when the output 13 is reduced. As the result, the signal quantity change of the output 13 is not accompanied with switching of the gamma characteristic.

Title: Fire checking circuit
Inventor: KUSANO SATOSHI
IPC: G08B29/14
Filed: 1981-09-25
Abstract: PURPOSE:To obtain a fire checking circuit of a printing magnet free from adverse effect by variations in the driving voltage of a driver with a higher reference voltage set by obtaining it from the power source of the driver. CONSTITUTION:The reference voltage V'b of a comparator CMP is the power source VP after subtracted by a Zener voltage VZD. When transistors Tr1-Trn are off, a comparison input voltage V'a comes so close to VP that the output voltage V'c of the CMP becomes low. But when one of the transistors Tr1-Trn is turned on, current flows through one of magnets to raise the voltage VL across both terminals to a level V'a>V'b. Therefore, if at least one of the transistors Tr1-Trn is on, V'c becomes a high voltage. In case a half impedance is  caused by any trouble of the transistors, CMP can detect the conduction thereof  as it is because of a higher value of the reference voltage V'b.
